Forming simulation and process optimization of inflatable strut reinforcement plate for automobile back door

Abstract

Abstract Taking a new energy SUV back door inflatable strut reinforcement plate as an example, three key process areas are set on the surface of the plate, and the structural characteristics and forming characteristics of each area are analyzed. On this basis, a finite element model is established. Preliminarily select the process parameters that meet the actual production requirements, use AutoForm to perform numerical simulation analysis of stamping forming, compare the forming quality of the product under the forming process and the drawing process, to achieve the purpose of process optimization, and then determine the final stamping process plan. Taking the maximum springback as the evaluation index, an orthogonal test with 4 factors and 3 levels is designed, and the parameter scheme with the best forming quality through the range analysis method provides a reference for the subsequent actual production of the part.
